IDIYERZIIGIB'LE HEADLIGHT] Application filed October 20, '1926. Serial No. 142,966.

to the left for the purpose of illuminating the path into which the machine is turning. An important object of the invention is to provide'means in a dirigible headlight operating mechanism for compensat ng between the relative movement of the chassis in relation to the axles.

With'the above and other objects in View as will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction herein described and claimed.

In thedrawing: Figure 1 is a front elevation of the dirigible headlights applied to an automobile the distant portions of the automob le being removed,

Fig. 2 is a plan view ofthe dirigible headlight mechanism, v

Fig. 3 is an enlarged rear elevatlon of'a portion ofthe mechanism of the apparatus,

Fig. 4: is a section on the line of Fig. 3, e

Fig. 6 is a transverse section therethrough, Fig. 7 is-a detail elevation of thelower end of one part thereof 1 I a F igure'8 is a detail view of the tripping lever,

line 9-9 of Figure 4.

Referring to the drawing by characters of reference, itwill be seen that A denotes the front axle of an automobile having the usual knuckles B,'the spindles C of which are supported on the front wheels D. A portion of the vehicle body has been shown at E and is mounted on springs after the usual way. The front mud guards have been indicated at VG. Extending rearwardly from the knuckles B carryingthe spindles G are arms H" connected by a cross-rod I' and another rod J connects this rod to the steering shaft, "not shown. The'mechanism thus far' de- -automobiles and does not, in itself, consti- Figure 9 is a sectlonal view taken on the scribed is the same as thatfound' on most tute any part of the present invention,

Headlights are 'denotedby the numerals 1* I and are operatlvely'connected' in any suitable manner with connecting rod 2 so that the reciprocation of this rod back and forth across the front of the automobile willre volve the headlights in a manner that is well known in this art. My previous patent heretofore referred to shows the'preferred embodiment for making this operative connection. The rod 2 is pivotally connected to the end of a crank 3 whichis rockably mounted as'at 4' on an inverted u-s haped member U which includes legs 5 and, 6 con ne'cted by bight 7. A tubular casing'8 receives the leg 6 and the leg -5'is disposed exteriorly thereof. The end of the leg 6 terminates in a head9 having tenons 10 on v opposite sides thereof for sliding. in morticesv 11 formed in the sides of the tubularfcasing- 1 8. The casing 8 is supported on'a laterally exgending pin 24: located intermediate its ens. a Securedto one portion of the'axle' isia bracket 17 adapted to be held in placeby a U-bolt 18 and a threaded bolt 19engaging the axle. "Obviously, however; any other fastening means, can be used- This bracket has anintegral body 20, the'bottom portion of which is grooved along a" line extending parallel with the longitudinal axisof the I axle A, the groovebein'g shown particularly at 21 in Fig. 4. A cover plate 22' serves to.

conceal the groove and is detachably secured on the bodyv Slidably mounted within this groove is 'a block 23 'from'whichextends the pin 24. slidable within theslot 25' in one side 'wall'of' the groove 21. This pin is integral with or fixedly secured to the back of the tubular casing 8 as previously indicated and isheld against rotation within the blockj23 by set screw 26 or the like.v A shaft 27 is' journ'aled within the body 2 and extends rearwardly therefrom, there being a recess 28 ,in the body and opening upwardly into groove 21; Acrank arm 29 is secured to the shaft 27 and is: mounted within the recess 28, the'u'pper end of this arm being in' engagement with the block 23 so that when the shaft is rotated back and forth the arm willproduce a back andlforth slidingmovement of block 23j'and a corre- 1 so that they'may be turned to the right or the left.
